22nd Street Sewer Augmentation

Pima County and its contractor, KE&G Construction, Inc., will begin work on the 22nd Street Sewer Augmentation project, which extends from Alvernon Way to Swan Road. This work is necessary because the existing pipe is at or near its maximum flow capacity. This project will install new sewer along 22nd Street from Alvernon Way to Swan Road, increasing sewer volume and improving the lifespan of the sewer infrastructure in the area.

The North Rillito Interceptor (NRI) project is approximately 10 miles long. The NRI is a large diameter pipeline that transports wastewater from the City's far east side in the Woodland Road and Bear Canyon area, along the north bank of the Tanque Verde Creek and Rillito River, to the Ina Road Wastewater Treatment Facility -- which serves a major portion of northern and eastern Tucson.
